Abstract

The invention relates to a ski stick, which comprises a hollow reinforced-plastic profile (10). In the inventive ski stick, a profile wall (11) contains at least one longitudinally extending reinforcement element (13), which is at least partially embedded in the manufacturing step of the profile (10) in the wall structure (11) as an integral part thereof. The reinforcement element (13) may extend along the entire length of the reinforced-plastic profile or partially along its length, and its cross-sectional form may be circular or longitudinal or angular, e.g. triangular.

Claims

exact text as granted — not AI-modified
I claim: 
     
       1. A ski stick comprising a hollow reinforced-plastic profile (10) having a profile wall (11) and at least one reinforcement element (13) extending in the longitudinal direction, said at least one reinforcement element (13) being at least partially embedded in the manufacturing step of the profile (10) in the profile wall (11) as an integral part thereof, said ski stick being manufactured by a pultrusion process in which the profile (10) is formed on top of said at least one reinforcement element (13). 
     
     
       2. A ski stick according to claim 1, comprising one reinforcement element (13) which extends partially or completely along the entire length of the stick (10). 
     
     
       3. A ski stick according to claim 1, comprising at least two reinforcement elements (13) which may each extend partially or completely along the entire length of the stick (10). 
     
     
       4. A ski stick according to claim 3, wherein the cross-section of the ski profile (10) is elliptic and said reinforcement elements (13) are placed on a longer axis line of the elliptical cross-section. 
     
     
       5. A ski stick according to claim 1, wherein said at least one reinforcement element (13) is hollow. 
     
     
       6. A ski stick according to claim 1, wherein said at least one reinforcement element (13) has a closed profile. 
     
     
       7. A ski stick according to claim 1, wherein said at least one reinforcement element (13) comprises a reinforced-plastic profile having a plastic portion and reinforcement fibers arranged therein. 
     
     
       8. A ski stick according to claim 1, wherein said at least one reinforcement element (13) comprises a material selected from the group consisting of metals, thermosetting and thermoplastic resins and wood. 
     
     
       9. A ski stick according to claim 7, wherein the plastic portion of the reinforced plastic comprises a material selected from the group consisting of nylon, polyesters, phenol resins, epoxy resins, vinyl ester resins, polycarbonates and polyolefines. 
     
     
       10. A ski stick according to claim 9, wherein the reinforcing fibers are selected from the group consisting of inorganic fibers, glass fibers, carbon fibers, boron fibers, ceramic fibers and metal fibers, and organic fibers, nylon, kevlar, polyester and polyolefine fibers. 
     
     
       11. A ski stick comprising a hollow reinforced-plastic profile (10) having a profile wall (11) and at least one reinforcement element (13) extending in the longitudinal direction, said at least one reinforcement element (13) being at least partially embedded in the manufacturing step of the profile (10) in the profile wall (11) as an integral part thereof, said profile having an elliptic cross-section, said at least one reinforcement element being arranged on a longer axis line of the elliptical cross-section. 
     
     
       12. A ski stick according to claim 11, comprising one reinforcement element (13) which extends partially or completely along the entire length of the stick (10). 
     
     
       13. A ski stick according to claim 11, comprising at least two reinforcement elements (13) which extends partially or completely along the entire length of the stick (10). 
     
     
       14. A ski stick according to claim 11, wherein said at least one reinforcement element (13) is hollow. 
     
     
       15. A ski stick according to claim 11, wherein said at least one reinforcement element (13) has a closed profile. 
     
     
       16. A ski stick according to claim 11, wherein said reinforcement element (13) comprises a reinforced plastic profile having a plastic portion and reinforcement fibers. 
     
     
       17. A ski stick according to claim 11, wherein said reinforcement element (13) comprises a material selected from the group consisting of metals, thermosetting resins, thermoplastic resins and wood. 
     
     
       18. A ski stick according to claim 16, wherein the plastic portion comprises a material selected from the group consisting of nylon, polyesters, phenol resins, epoxy resins, vinyl ester resins, polycarbonates and polyolefines. 
     
     
       19. A ski stick according to claim 18, wherein the reinforcing fibers are selected from the group consisting of inorganic fibers, glass fibers, carbon fibers, boron fibers, ceramic fibers, metal fibers, organic fibers, as nylon, kevlar, polyester and polyolefine fibers.
